Kernel-4.18.0-80.el8_nxp,pca9685-pw

NXP PCA9685 16-channel 12-bit PWM LED controller

Required properties:

• compatible: “nxp,pca9685-pwm”
• #pwm-cells: Should be 2. See pwm.txt in this directory for a description of
  the cells format.
  The index 16 is the ALLCALL channel, that sets all PWM channels at the same
  time.

Optional properties:

• invert (bool): boolean to enable inverted logic
• open-drain (bool): boolean to configure outputs with open-drain structure;

         if omitted use totem-pole structure
  

Example:

For LEDs that are directly connected to the PCA, the following setting is
applicable:

pca: pca@41 {
compatible = “nxp,pca9685-pwm”;
#pwm-cells = <2>;
reg = <0x41>;
invert;
open-drain;
};
